My car has about 26k miles on it and I was getting about 300 miles on about 12.5 gallons. Well I figured I would try some fuel injector cleaner and it really helped.
The first two are before the cleaner, it is the same drive and drive style.

 

wow...thats a big difference

 

yeah, i was excited...its never got that kind of MPG

 

damn. I get about 300 miles per a tank when i go easy. what kind of cleaner did you use?

 

it was the Preston complete fuel system cleaner

 

where did u get that kit

 

i wanna throw a bottle of TUMS into my gas tank and see what it does.

 

i think Maalox might work better...lol

 

hows your driving style (agressive, calm, etc). Cuz i get 380 miles on full tank on my tc and i drive normal (sometimes agressive, most of the time calm). 05 tc with 35k miles

i also shift at 2500 all the time. i think i could have gone for 10 more but i could feel the car would struggle to start when i cranked the ignition.

 

I run it up to 3400-4000 about 75% of the time. The other 25% of the time is 2K or below.
I get about 16-20mpg. Never any higher...
05 tC w/ 52K

 

how the hell do you get that kind of mileage?!!? i can take it easy on my tc an get 280 at the best...

 

I'm kinda getting a sneaking suspicion that it was abused before I got it from the dealership at 50K miles... Also finding tons of things they lied to me on (not sure if that stems from the incompetent sales person or not)

 

I get about 330 miles with my 2007 auto + Injen CAI and normal-ish driving (occasionally hard).

 

no car is gonna have the same results, with different altitudes and climates.. these are small things in effects that will always change the results, included with everyones different driving style.. some people are more aggressive then others, wear and tear on your vehicle, and your vehicles tires.. tire psi.. these are all things that will change your gas mileage.. air intake and exhaust mods.. (assuming you dont drive aggresively when you get them) will help with your gas mileage too..

 

i get like 260 tops!!!!!!!!

 

for me: only city and its like 320 mile all the time

and not grandma style but im not pushing it really hard.

 

I get about 300 per tank with aggressive driving.

 

Used to average 22mpg, 75% city 25% highway. Now I average 23. But have to use 91.

 

Use the scanguage to measure this.

Average 28.3= ~370 miles per full tank with 1.5 gallons left

Shift at 3k every gear.

 

x 2 ???
